Profile: The 23-year-old outfielder has all of 13 plate appearances to his name over two cups of coffee with the Nationals. He possesses limited power, but has shown fantastic speed in the minors, stealing as many as 64 bases back in 2010. He makes respectable contact, but his impatience has led to meager walk rates, which will cap his offensive upside. With a full outfield in Washington, he'll be lucky to crack the opening day roster. Even a slew of injuries might not be enough to give him consistent playing time. Thus, he could be safely ignored in fantasy leagues. (Mike Podhorzer)

The Quick Opinion: If Perez somehow lucked into some playing time, his speed could actually earn him some NL-Only value. But that's unlikely to happen given the team's current crop of outfielders and bench bats.

Profile: Non-tendered by the Braves in early December, Perez will be joining the Astros in Spring Training. He should see some time in Houston at some point as an injury fill-in, and when he does, you can nab him for the few steals that he will provide before he’s sent back to Triple-A. (Darren Schienbein)
